以RS数据为数据源,基于GIS平台,分析了友谊农场2004～2011年水田的时空变化情况,旨在为区域种植业结构优化及农业发展提供依据。主要结论如下:2004～2011年,友谊农场水田田块数量大幅增加,田块规模不断扩大,水田总面积快速增加,占耕地比重迅速提升。水田扩张在空间上呈现“增生式”。截至2011年,水田面积达到了6.01万hm2,占耕地总面积的42.25%,友谊农场水田分布形成了东密西疏的宏观格局。今后,应在充分客观评估水土资源承载力的基础上适度开发水田,优化配置各种农业物资、农业科技人员与农业劳动力,促进农业可持续发展。
Taking RS data as data source and GIS platform, the temporal and spatial changes of paddy fields in Friendship Farm from 2004 to 2011 were analyzed to provide the basis for regional cropping structure optimization and agricultural development. The main conclusions are as follows: From 2004 to 2011, the number of paddy field plots in Youyi Farm increased significantly, the field plots expanded continuously, the total paddy field increased rapidly, and the proportion of cultivated land increased rapidly. Paddy field expansion in the spatial rendering “proliferation of ”. As of 2011, the paddy field area reached 60,100 hm2, accounting for 42.25% of the total cultivated land area. The distribution of paddy fields at Friendship Farm formed a macro-pattern of the east and the west. In the future, paddy fields should be properly developed on the basis of full and objective assessment of the carrying capacity of water and land resources, and various agricultural materials, agricultural science and technology personnel and agricultural labor should be optimally allocated so as to promote the sustainable development of agriculture.
